[metapost] macro path

[Steve MC Han]

Hi,  I have trouble with metapost. Could someone give some insight for this?
   
  This is the error message.
   
  <<! Unable to make mpx file.
l.78 label.bot(btex
                    $\hbox{\sf Rectangle}$ etex, (0,-.6u));
6 output files written: 2MS4.1 .. 2MS4.8
Transcript written on 2MS4.log.>>
   
  So, I tried set the path straight by typing "c:\TexLive2007\bin\win32" at command prompt, it magically worked. But with different file, I still have trouble with similar error message. This time, even with set path like above, it didn't work.
   
  <<mpost --tex=latex 2MS3
This is MetaPost, Version 0.993 (Web2C 7.5.6)

  >> 2MS3.mp

! Unable to make mpx file.
l.156 label.lft(btex
                     $A$ etex, z8);

  This trouble started after I did "mptopdf". At first, mptopdf didn't create pdf files even thoufgh there was no error message. So, by consulting Contex conversion to pdf manual 
   
  http://tex.aanhet.net/context/mirror/general/sources/mptopdf.pdf
   
  I typed "pdftex --ini mptopdf" at prompt command and after that it produced pdf files but now mpost didn't work with the above error message. I think path
   
  c:/TeXLive2007/texmf-var/fonts/map/dvips/updmap/psfonts.map
   
  is screwed up somehow.

That is all excellent advice, thank you. The texhash brought success
with the file in texmf-dist, but not when put in texmf-local. I have
tried changes to texmf.cnf as directed in 

http:/www.ctan.org/installationadvice#installationguidelines

but no success yet. As newb to both TexLive and Linux, there is much to
learn, but I sense there is something obvious I am missing. Sorry this
is off MPost topic per se, and thanks for your tolerance.
